GRAN-CLEANER ATTACHMENT THRASHING MACHINES.

Application filed April 21,

To all w hom t may concern,

Be it known that I, Moses J. DoRAN, a citizen of the United States ofAmerica, residing at Pierpont, in the county of Aishtabula and State ofOhio, have invented certain new and useful Improvements in Grain-CleanerAttachments for Thrashing Machines, of which the following is aspeciication. I

The primary object of the present invention is to provide agrain-separating spout adapted for oscillatory suspension within athrashing machine spout for the reception of the thrashed grain as itleaves the machine and whereby clean grain may be bagged at thethrashing machine which will not require further cleaning or separating.

A further object of the invention is the provision of an auxiliary spoutfor receiving the grain from a thrashing machine for separating andconducting clean grain to one side of the machine and the waste to theother side thereof, my device being adapted for agitation by connectionwith a movable part of vthe machinery of the thrashingmachine with whichthe deviceis employed.

A still further object of the invent-ion is to provide a separatingspout that is simple in construction, easy and inexpensive tomanufacture and may be easily installed upon an ordinary thrashingmachine for the final separation and `cleaning of the grain from thechaff.

With these objects in view theinvention consists of the combination andarrangement of parts hereinafter more fully de'- scribed in connectionwith the accompanying drawing andin which like reference charactersdesignate corresponding parts throughout the several views.

In the drawing,

Figure 1 is a side elevational view of the invention illustrating indotted lines a manner of suspending and oscillating the same,

Figure 2 is a central longitudinal sectional view thereof,

Figure 3 is a top plan view of the same,

Figure l is a transverse sectional view taken upon line IV-IV of 'Figure1, and

Figure 5 is a similar sectional view taken upon line V-V of Figure 1.-

Referring more in detail to the drawing, it will be understood that myinvention is an attachment for use within the grain spout of a thrashingmachine and broadly 1921. Serial No. 463,259.

consists of an auxiliary spout having opposite sides 10 and 11 with aninclined bottom 12, and a sieve vor screen 13 oppositely inclined abovethe bottom 12, for receiving grain directly thereon. rlhe sides 10 and11 are adj ustably connected together by four transverse bolts 14khaving heads 15 outwardly of the side 11 with winged nuts 16 threadedupon the opposite ends of the ybolts outwardly of the side 10.

The screen 13 is pivoted adjacent its higher end 17 upon one of theupper bolts 14: and extends between the sides 10 and 11 beneath thecorresponding upper bolt at the opposite end of the spout while thebottom board 12 rests with its lower end 18 upon the bolt let beneaththe end 17 of the screen and with the upper end of the bottom 12 betweenthe sides 10 and 11 at a considerable distance inwardly of the lower endof the screen 13. The bottoniv 12 and screen 13 are maintainedadjustably inclined in opposite directions by tightening the nuts 16upon the bolts 1li, thereby securing the same between the sides 10 and11.

vThe screen being adapted for the reception of grain, the device isdesigned for suspension for ready oscillation within the discharge spoutof thrashing machine and suspending members such as hooks 19 illustratedby dotted lines may be employed for this purpose engaging beneath theupper corner extensions 2O of the sides 10 and 11. The draft from, thethrashing machine serves to blow away the 'chaff and vwaste which withthe grain travel upon thescreen 13 toward the lower end 21 thereof when4the device is longitudinally oscillated as by -means of a pitman 22herein illustrated by dotted lines adapted for connection with anysuitable moving part of the operating mechanism of the thrashingmachine.

i grain saver is provided adjacent the lower end of the screen 13,consisting of a metallic shelf 23 beneath the foraminous member 24E ofthe screen 13 and oppositely inclined whereby grain passing through theforaminous member 24 beyond the sides 10 and 11 falls upon the shelf 23and by reason of the oscillations of the device the grain passes to theinclined bottom 12 and is discharged at the lower end 1S thereof forbagging. Suitable cross braces 25 are provided for the screen `13 and itwill be evident that the relative inclination of the screen 13 andbottom 12 may be changed as found de sii-able as indicated by dottedlines in Figure 2, of the drawing. The shelf 23 has an end wall 26engaging the foraminous member 24; at the lower end 21 of the screen 13so that the shelf 23 collects and saves all of the grain that would beotherwise lost by falling outwardly of this end of the auxiliary spout.The lower end of the shelf 23 is adapted to overlie the upper end of theinclined bottom 12 thereby constituting in reality a continuation of thebottom 12. It will thus be seen that the grain passing' from the shell23 will fall onto the inclined bottom 12 to be discharged at the lowerend 18. By so providing the screen 13 with the shelf 23 the cost ofproduction of the entire device will be greatly decreased. It willalleviate the necessity of providing a bottom 12 and side walls 10 and11 of the same length as the screen 13 and at the same time will providea relatively long screening surface Q4 for the screen 13.

The complete operation of the invention will be fully understood fromthis detailed description thereof, and while the form of the inventionherein set forth is believed preferable, it will be understood thatchanges may be made therein without departing from the spirit and scopeof my invention.

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, is

1. An auxiliary grain spout comprising side walls, an inclined screenpivoted at its upper end between said walls and extending beyond saidwalls at the opposite end of the device, an inclined bottom positionedbetween said side walls and a shelf beneath the lower end of the screenadapted for dis charge upon said bottom.

2. An auxiliary grain spout comprising side walls having upper endextensions, upper and lower bolts adjustably connected between saidwalls, a screen member pivoted upon one of said upper bolts and beneaththe other upper bolt extending longitudinally between said walls, aninclined bottom board beneath the screen with its lower end positionedupon one of said bolts beneath said upper pivoting bolt and an inclinedshelf beneath the lower end of the screen overlying the upper end ofsaid bottom board.

A grain spout adapted for oscillatory movement comprising sides, ascreen of greater length than said sides positioned therebetween, a boltconnected through said sides pivotally engaging the upper end of thescreen, an adjusting bolt secured between said sides adjacent theopposite end of the device positioned above said screen, an adjustablebottom board oppositely inclined beneath the screen and a shelf beneaththe screen having a discharge end above said board.

4t. A grain spout adapted for oscillatory movement comprising sides', ascreen of greater length than said sides positioned therebetween, a boltconnected through said sides pivotally engaging the upper end of thescreen, an adjusting bolt secured between said sides adjacent theopposite end of i the device positioned above said screen, a

shelf beneath the lower end of the screen having a closed end portionengaging the screen, the shelf being inclined downwardly toward thepivotal end of the screen and a bottom board beneath the screen andshelf adjustably positioned between said sides.

5. A grain spout adapted for oscillatory movement comprising sides, ascreen of greater length than said sides positioned therebetween, a boltconnected through said sides pivotally engaging the upper end of thescreen, an adjusting bolt secured between said sides adjacent theopposite end of the device positioned above said screen, a shelf beneaththe lower end of the screen having a closed end portion engaging thescreen, theshelf being inclined downwardly toward the pivotal end of thescreen, a bottom board beneath the screen and shelf adjustablypositioned between said sides, a lower bolt between said sides beneaththe pivoting bolt, a bottom board oppositely inclined with respect tothe screen positioned beneath the screen with its lower end upon saidbottom bolt and adjustable retaining means between the sides beneath theopposite end of said board.

In testimony whereof I atix my signature.

MOSES J. DORAN.
